The power supply can be changed over between the "sngle-
phase, 100V to 120V" and "3-phase 200V to 240V" by carryng
out the followng two steps.
1 Replacement of the power cord
2 Change-round of the changeover connector on the FLT PWB.
1) Turn OFF the power supply wth the power swtch after con-
firming that the sewing machine has stopped.

[In the case the single-phase, 100V to 120V power supply is
1
used]
Connect the AC power supply to the black and whte wres of the
power cord plug and the earth wre to the green/yellow wre.
For the operaton wth the sngle-phase power supply, the red wre
does not need to be connected. Consequently, cut both ends of
the wre at the bottom of the cord.
[In the case the 3-phase, 200V to 240V power supply is used]
Connect the AC power supply to the black, whte and red wres of
the power cord plug and the earth wre to the green/yellow wre.
